In this thesis the results of a detailed experimental study of the chemistry induced by irradiation of ice maniies by electrons and ions are presented. This research is directed towards gaining a better understanding of the mechanisms by which molecules are S3 nthesised in the Interstellar Medium (ISM) and lunar surfaces. Several experiments explored the formation of ozone in such ice mandes, since the ozone in any planetaiy or lunar atmosphere has been suggested as biomarker in die search for life. However recent space missions have revealed ozone on several Samrnian moons and Jupiter's Ganymede. In this thesis we show that ozone is readily produced abiodcally by irradiation of oxygen, carbon dioxide, nitrous oxide and nitrogen dioxide ices. These results have important implications for the use of ozone as a biomarker in the search for life on extraterrestrial planets.
